Unproved treatments are putting patients at risk
“Medical tourism” for unproved uses of stem cell therapy poses potential risks to patients. They may spend tens of thousands of pounds in the hope of an effective treatment for chronic degenerative conditions such as Parkinson’s disease, multiple sclerosis, and some forms of retinal disease, say a group of UK experts. They warn that the technology is being widely and inappropriately used in therapeutic areas where there is little or no evidence of benefit and where the chances of success are many years or even decades away.
